UPDATE: Arizona father and daugher identified in fatal south Highway 101 crash

An Arizona man and his 3-year-old daughter were killed in a crash on Highway 101 south of Ukiah just after 11 this morning, and the Santa Rosa driver of the van that struck them was arrested on suspicion of manslaughter, according to the California Highway Patrol.

The father and daughter who died were identified as Jonathan James Arroyo, 26, and Taylor Arroyo, 3, according to the Mendocino County Sheriff-Coroner's Office.

Arroyo, his wife and two daughters were headed south on Highway 101 south of Burke Hill Road when their four-door Cadillac sedan was sruck by a northbound Chevrolet Express cargo van that crossed the grass median for reasons still under investigation, according to the CHP.

The driver of the Chevrolet van, identified by the CHP as Emmanuel Ariel Mandujano Barajas, 22, was uninjured. He was seen sitting in the back of a patrol car being questioned by officers at the scene, and the CHP later reported he was arrested on suspicion of felony manslaughter in the incident.

The CHP had not determined by the close of business Thursday whether alcohol or other drugs factored in the collision.
